Notes.The columns are: (1) number of position in Fig. 3, asterisk marks where a secondary line component was found and subtracted before the calculations; (2, 3) right ascension and declination offsets; (4) linewidth from HFS line profile fit; (5) optical depth; (6) kinetic temperature; (7) excitation temperature; (8) rotation temperature; (9, 10) NH3 column density from the primary and the secondary components respectively; (11) H2 volume density; and (12, 13) Herschel H2 column density and colour temperature. Numbers in the first column refer to the marked positions in Fig. 3a and asterisk indicates where a secondary line component was found.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
